ting Apparatus for Harvesting-Machines, of4

which the following is a specification.

My invention is an improved cutting apparatus for harvestingmachines, the object of my invention being to provide an improved endless traveling chain which carries the cutter plates, and thereby relieve the cuttingi apparatus of the jar and rattling stress inci dent to the operation of the reciprocating cut`` ter-bars usually employed in machines of thisj class.

My invention consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.`

In the accompanying drawings, 'Figure 1 is a top plan view of 'a cut-ting apparatus con-E structed in accordance with myinvention andthe coacting parts of a harvesting-machine.;

Fig. 2 is a vertical transverse sectional view taken on the line a a, of Fig. 1. Fig. 3 is a detail sectional view taken on the line b b of Fig. 1. Fig. 4 is a similar view taken on the line c c of Fig. 1. Fig. 5 is a detail perspective view of one of the endless traveling cutter-plates. Fig. 6 is a detail perspective view.

The base-plate 1, which supports the cutting apparatus, is provided at its inner end with a bearing 2 for the lower end of a short vertical shaft 3, on which is fixed a sprocketwheel 4 and a gear-wheel 5. wheel is disposed on the upper side of the plate 1, and said gear-wheel is above said'- sprocket-wheel. A bracket 6, which is secured on the inner end ofthe said plate 1, has a bearing 7 for the upper portion of the said `shaft 3 and is further provided with a bearing S for a counter-shaft 9,`which projects forward from the harvesting-machine (not shown) and is provided with'a gear-wheel 10, which meshes with thel gear 5, and thereby rotates the same, together with the said sprocket-wheel 4. In the outer end of the base-plate 1 is an elongated slot 1l. Abracket 12 is bolted on said plate 1, near the outer end thereof, has a slot 13 disposed over the slot 11, and is provided with an adjustable bearing 14 for the upper portion of a short vertical Said sprocket shaft 15, on which rotates a sprocket-wheel 16; The said shaft passes through the slots "11 13, and the lower portion thereof is engaged by an adjustable bearing 17. Said bearings 14 17 are adj usted by means of screws 18, which operate in threaded openings in bosses 19 20, with which the bracket 12 and the plate 1 are respectively provided.

`An endless traveling chain 21 connects the sprocket-wheels 4 16. The said chain is com= posed of metallic blocks 22 and links 23, which kconnect the said blocks. The latter are of the form shown, and each of the same is formed integrally with a cutter-'plate 24, the said cutter-plates projecting from the outer sides of the saidblocks. Each cutter-plate -has on one side an obliquely-disposed serrated cutting edge 25. The length of the blocks 22 and links 23 is such that the sprockets or spurs Yofthe sprocket-wheels engage the spaces between the said blocks. Said links 23 are on the upper and lower sides of the said blocks 22,' andthe spurs ofthe sprocket-Wheels pass between the saidlinks, as will be understood. The' shaft 15, which carries the sprocket wheel 16 at the outer end of the base-plate,

being adjustable by the means hereinbefore described, the endless traveling cutter-chain may -be maintained at all times at the requi- 1f site tension, as will be understood.

Aiinger-bar 26 is disposed in front of the plate 1 and supported and connected to said vplate by suitable metallic straps 27, which are bolted to the under side of said fingerbar and to the under side of said plate. fingers 28, which are carried bythe said fingerbar, are of suitable construction and are provided in their rear sides with open slots 29, through which the cutter-plates pass, the said fingers coacting with the said cutter-plates in cutting the grain, as will be understood. Above the finger-bar and connected to the rearward-extending upper arms 30 of the 1ingers is abar 31. Arunway is formed between the said finger-bar 26 and said bar 31 for the cutterplates on the `front operative lead of the chain, the said front lead of the chain operating in the runway formed between the front side of the base-plate 1 and the rear sides of the finger-bar 26 and bar 31. A bar 32 is supported above the front portion of the baseplate 1 and `bears against the rear side The IOO

of the front lead of the cutter-chain, the said bar 32, together with the front side of the said base-plate 1, keeping the said front lead of the cutter-chain straight, and hence maintaining the cutter-plates in operative relation to the ngers under all conditions.

An auxiliary platform conveyerSB, which comprises an endless traveling apron 34 and rollers 35 36, is disposed above the base-plate 1 and extends 'from end to end thereof between the sprocket-Wheels. The said rollers are journaled in bearings 37, and the roller 3G has a spur-pinion 37' at its front end, which is engaged by a spur-Wheel 38 on the front end of an operating-shaft 39. The latter projects forward from the frame, of the harvesting-machine (not shown) and uudertlie plate l, and the spur-wheel 38. operates through a slot 40., which is made in the said plate l.y The function of Said shaft 39 and said gears 87 38 is to cause the upperlead ofthe auxiliary plat form oouveyer to travel in the direction indi- The platform @envoyer 41, which is ofthe usual construction1 is disposed in rear of the auxiliary platform conveyor, and au angle-*bar 42iwl1ioh has bearings for the journals at the front ends of certain of the rollers 43 of ,said platform eenveyer is disposed between the front side of the platform conveyor ,andl the rear lead of the endless traveling cutterchaio Said augle-bar 42 is interposed between the cutter-` Dlaiee. on the rear lead of the said cutterehain and the said platform conveyor 4:1 and for-m. a shield for the latter. The said platform conveyor 41 and auxiliary conveyor 3 3 convey the grain as the same is out tothe I usual elevating-conveyer, (not here shown, as

gers, an auxiliary platform conveyerdisposed between the leads of said chain and a platform conveyor in' rear of said auxiliary conveyor, substantially as described.

2. In a harvester, the combination of an endless traveling cutting mechanism having front and rear leads, an auxiliary platform conveyor disposedl between the leads oif the cuttingxneohanism, and a platform conveyor in rear of said auxiliary conveyer, substaptially as described- 3. In a cutting apparatus of the class described, the combination of a base-plate, slprocl'ret-Wheels, au endless traveling cutter-chain connecting and operated by said sprocket-Wheels, the front and rear leads of said cutter-chain operating on the front and reary sides. of said base-plate, a bar 32 on the front side of said base-plate bearing against the rear side of the front lead of said chain, cutter-plates carried by said chain, a fingerbar supported in ,front of said base-plate, iingers onisaid finger-bar having open slots in which the said cutter-plates. operate, and a bar 31 secured to the said fingers, said bar ccacting with said finger-bar to form a racevvay for the said cutter-plates, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in the presence of two witnesses,

SYLVESTER BARINGER.
